2021: Utility Scale Batteries Are Shifting Purpose

What is happening? EIA Annual Electric Generator Report shows utility scale battery projects are being deployed 59% for frequency regulation, 39% for ramping or spinning reserve, 37% for arbitrage, 26% for load following, 17% for excess wind and solar, 15% for system peak shaving

Why is this important? “Frequency regulation remains the most common use for batteries, but other uses, such as ramping, arbitrage, and load following, are becoming more common as more batteries are added to the electric grid.”

How will this be important? Watch the percentages
